Blockscout: feat request: show block header extradata

[hadv]

For ethereum mainnet and some other mining consensus, it'd better to show the miner.extradata to show miner's name or voting

[vbaranov]

We display validators names for the chains where we know who are the validators, for example, for xDai, POA Core, Sokol. Anyone can check this data from https://validators.poa.network for POA-based networks. Do you know a single point of truth to check who are the miners/validators for Ethereum Mainnet or for other networks?

AFAIK, on the ethereum mainnet, miner can arbitrary set the extradata by specific in the geth cmd's --miner.extradata, I dont know any truth point. by the way, on the PoW we dont need truth because it include the extradata on the block header.

Ethereum PoW miner now can make a vote to switch to ProgPoW by adding PPYE in block's extradata that they mined successfully.

I'd very much like to see this as well. Miner's use this field to identify themselves and / or to encode text in the blockchain.

There is indeed a single point of truth to check the miners and that is within the blockchain itself. There are mining pools, there are solo miners. These miners come and go, but they are all able to set the extradata field arbitrarily, and it may change from block to block.

Specifically, I would like to see it within the Miner box in the Block Details screen:

All chains would benefit from this, and it also helps for miners to know which pool mined which block, without having to memorize the wallet address.
